How to solve level 719, step by step

After every placed cat, cross out the rest of its row, its column, its patch and the four corner squares around it. The steps below assume you do (the in-game auto-paws assist does it for you).

1. Cat 1 of 10: the yellow patch is down to a single free square at row 1, column 10, so its cat settles there.
2. Cat 2 of 10: the lime patch is down to a single free square at row 9, column 1, so its cat settles there.
3. Every free square of the coral patch sits in row 8, so the coral cat must come from there and the rest of row 8 can be crossed out. Row 10 only has free squares inside the periwinkle patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 2, column 7 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 3, column 4 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 3, column 7 would leave the sky patch with no home for its cat, so cross that square out. Every free square of the mint patch sits in row 4, so the mint cat must come from there and the rest of row 4 can be crossed out. A cat at row 2, column 6 would leave the rose patch with no home for its cat, so cross that square out. Every free square of the sky patch sits in column 8, so the sky cat must come from there and the rest of column 8 can be crossed out. Cat 3 of 10: the mint patch is down to a single free square at row 4, column 7, so its cat settles there.
4. Cat 4 of 10: the sky patch is down to a single free square at row 2, column 8, so its cat settles there.
5. Cat 5 of 10: the rose patch is down to a single free square at row 3, column 5, so its cat settles there.
6. Cat 6 of 10: the lilac patch is down to a single free square at row 5, column 3, so its cat settles there.
7. Cat 7 of 10: the coral patch is down to a single free square at row 8, column 9, so its cat settles there.
8. Cat 8 of 10: the only free square left in row 6 is column 6, so the cat goes there.
9. Cat 9 of 10: the periwinkle patch is down to a single free square at row 10, column 4, so its cat settles there.
10. Cat 10 of 10: the aqua patch is down to a single free square at row 7, column 2, so its cat settles there.
